' of which the following is a specificatiom.

This invention relates to a device for mixing emulsions;

The invention relates more particularly to devices in which the mixing is efiected by means of stepped cones, that is to say, the fluid to be ground, is pressed through the seat of a cone or of a valve which itself, in the same Way as its seat, consists of single steps, as described in the U. S. Patent 1062554. In order to enable the size of the slot or gap between the .single'steps of the cone to be regulated, a solid cone with several steps was hitherto used while the valve seats were adjustable relatively to each other. According to this invention, the cone is formed of single sections adjustable relatively to each other, in such manner that each single part is adjustable relatively to the others, and in that way the size of the slot or gap can be adjusted independently. This device makes it possible to regulate exactly the slots and therefore the activity in the single stages, and to grind the working surfaces accurately. Moreover, liquids or gases can be introduced. between the single steps during the operation. The invention relates both to devices in which this cone is stationary, and to devices in which it is rotated inany desired manner. This r0- tatio-n can be effected either by providing the cone in the known manner with helical screw-thread or blades on which the liquid first into hollow spacesto be ground acts as in a turbine, or the cone can be supported by a spindle which is .guided outward and provided with a driving pulley by means of which it can be rotated. The single steps of the cone can have straight or oblique surfaces. The liquid escaping from the surfaces preferably passes in which a mixing of the liquid takes place, which also prevents the fine liquid jets from impinging direct against the metalsurfaces and thus damaging it. v

A device according to this invention is Specification of Letters Patent.

illustrated by way of example in the accompanying drawing in which Figure 1 is a vertical section, Fig. 2 a section on the line A-B of Fig. 1, and Fig. 3- is a section on the line CD of Fig. 1.

As shown in the drawing, the cone has four'working surfaces 6 b b 6* and the casing has also a corresponding num nular spaces c e e a The cone pressed on with heavy pressure, consists according to this inventiom'of four sections (2 (Z d and d screwed into each other. To that end, the upper end of each single cone section is provided with a screwthread m m m with which it engages with the corresponding tapped thread of the superposed cone section. The perforationof each cone carrying the tapped thread, is exactly cylindrical at n n and a so that the single cones can fit exactly into each other. Tn this apparatus any desired number of conical surfaces can be screwed into each other'in the manner described; The several conical sections thus tightly screwed together form practically. one solid member. -This member fits into the casing in such a manner that the working surfaces on the several conical sections coact with corresponding working surfaces located within the casing.

The term two coacting members as used in the claims applies to those members carry- *r of aning a series of working-surfaces coacting with a corresponding series of working surfaces carried by the other. The grinding in of the working surfaces of the cones is effected by the single cone sections being first screwed together and turned as a whole in such a manner a curately as possible to the corresponding that they correspond as working surfaces of the casing. The absolutely accurate grinding in then takes place, so that during the grinding process all the working surfaces grind simultaneously.

When the grinding process is completed, the

cone is removed, divided into its single sec' slightly larger thanthe next a andso on. i

"' @In the construction illustrated, the casing is provided in addition'to the inletconduit slot-oz is slightly I a, with two further inlet branches a and a the former of which opens into the hollow chamber 6 and the latter into the hollow chamber a These inlet branches make it possible to supply to the emulsion to be treated, certain ingredients such as gases, liquids or even solid substances, for instance, those acting as catalyzers, when it is desired to impart to the fats treated special properties, for instance higher melting points or the like. When liquid is introduced through the branches in question, the slots 0: a of, etc, are of course adjusted in such manner that the increase of liquid or other substance should bealso taken into account, so that approximately the same work of emulsioning is performed at each working stage.

The cone is guided in the casing by making its bottom end triangular as shown in Fig. 3. The edges of the triang18 .are -however turned cylindrically,, so that they have, proper guidance in thex'inlet pipe a. The uppermost cone d is provided at the circumference with grooves 0 and for the rest turned to suit exactly the inner wall of the casing, so that the liquid can escape only through the grooves 0. In any case, the cone can also rotate, and to that purpose to be driven positively from the outside, or rotated by the liquid itself. I i

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In a device for mixing emulsions, the combination of two coacting members, means for introducing and discharging liquid, means for introducing matter at a plurality of points between said coacting members, and means for independently adjusting and setting the said members.

2. In a device for mixing emulsions, the combination of two coacting members, one of said members being provided with annular grooves adjacent to the Working surfaces, means for introducing and discharging liquid, means for introducing matter 7 at a plurality of points between said coacting members, and means for independently adjusting and setting the said members.
